TIE PLATE.

Application filed October 1, 1921.

vented a new and Improved Tie Plate, of

which the following is a full, clear, and exact description.

This invention relates to improvements in tie plates, an object of the invention being to provide a device of this character which will provide a relatively wide bearing surface for railroad rails, and which is provided means for preventing its displacement upon a tie.

A further object is to provide a tie plate so constructed that it will tend to greatly lengthen the life of ties upon which it is used and a plate which will be simple and practical in construction, durable and efficient in use, and comparatively inexpensive to manufacture.

IVith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings:

Figure l is a top plan view showing my improved tie plate in applied position;

Figure 2 is a view in transverse section on the line 22 of Figure 1, showing the manner of supporting the rail upon the plate; and

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Referring in-detail to the drawings, ,1 represents a conventional type of wooden cross tie and 2 designates a railroad rail provided with the customary base flanges 3. It is customary in laying railways to interpose a tie plate between the rail and tie and my improved plate, designated by the reference numeral 4, embodies certain novel features which make it peculiarly adapted for this purpose. The plate at its forward and rear edges is formed with integral depending flanges 5 which embrace the tie and prevent s0 accidental movement of the plate in either direction. The under face of the plate is formed with a series of parallel diagonally extending sharpened corrugations or ribs 6 which dig into the tie and cooperate with Specification of Letters Patent.

the flanges 5 to prevent displacement of the plate.

Adjacent one side of the plate 4 extending from the forward to the rear edge thereof, is a beveled shoulder 7 which includes a flat face 8 presented toward the center of the plate. The outside base flange 3 of the rail 2 abuts against this shoulder and the rail is firmly held in place against the shoulder by conventional spikes 9 clamping the rail against the plate and driven through the squared openings 10 in the tie plate and shoulder for their reception.

The plate is also provided with a series of circular openings 11 arranged in convenient positions which permit the air to come in contact with the tie 1, thereby tending to prevent the tie from rotting under the tie plate.

It will be readily seen that the weight of trains upon the rail 2 will quickly seat the sharpened ribs in the tie. These ribs do not run with the grain of the wood in the tie and are therefore unlikely to split the same. The flanges 5 embracing the sides of the tie tend to brace the same against splitting as well as firmly holding the tie plate in place.

Although I have illustrated one of the preferred embodiments of my invention it will be apparent that various slight changes and alterations might be made in the general form and arrangement of the parts described without departing from the invention, and hence I do not wish to limit myself to the precise details of construction, but shall consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claim.

I claim:

As a new article of manufacture, a tie plate including depending defining tie embracing flanges at opposite sides thereof, a plurality of relatively sharp parallel ribs diagonally extending from one side to the other upon the under face of the plate adapted to dig into a tie, and a beveled rail engaging flange upon the upper face of the plate having slotted openings at its rail engaging side adapted to receive spikes, said plate being provided with a plurality of ventilating holes to permit the air to enter the under face of the base and the tie portion thereunder.
